OSHA Heat Program: What Employers Need to Know About the National Emphasis Program
For the first time in its history, OSHA has implemented a National Emphasis Program (NEP) focused solely on protecting workers from heat-related illnesses. This OSHA heat program introduces new enforcement protocols, enabling the agency to inspect high-risk workplaces before a single injury occurs.
Why the OSHA Heat Program Matters
Each year, more than 3,500 workers suffer heat-related injuries, many of which are entirely preventable. As climate patterns shift and heat waves become more frequent, OSHA’s heat program represents a pivotal step toward long-term worker safety.
According to Secretary of Labor Marty Walsh:
“The three-year average of workplace deaths caused by heat has doubled since the early 1990s… Heat illness presents a growing hazard for millions of workers.”
From construction sites in Texas to warehouses in Pennsylvania, the danger isn’t confined to a single industry or region. The OSHA heat program targets all high-risk environments—indoors and out.
Key Goals of the National Emphasis Program (NEP)
The OSHA heat program enables inspectors to proactively evaluate worksites with high exposure risk. Rather than waiting for incidents to occur, OSHA can now initiate inspections based on:
-
• Heat index forecasts above 80°F
-
• National Weather Service heat advisories
-
• Visible signs of heat hazards during unrelated inspections
-
• Referrals from other Department of Labor divisions
These inspections will focus on industries such as construction, maritime, agriculture, and warehousing, where heat exposure is most common.
What Inspectors Will Look For
Under the NEP, OSHA field staff will:
-
• Review incident reports for past heat-related injuries
-
• Interview workers for symptoms of heat stress or exhaustion
-
• Evaluate the presence of a heat prevention plan, including:
-
• Access to water, rest, and shade
-
• Employee training
-
• Acclimatization protocols for new or returning workers
-
Employers that fail to demonstrate a proactive safety plan could face compliance issues—or worse, leave their team vulnerable to serious injury.
What Employers Should Do Now
If your business operates in a high-risk industry, it’s critical to prepare now. OSHA’s heat program is active as of April 8, 2022, and will remain in effect for three years—unless extended or replaced.
Here’s how to get ahead:
-
• Audit your current heat safety policies
-
• Implement formal training programs focused on heat illness prevention
-
• Ensure break schedules, hydration stations, and shaded rest areas are available
-
• Update incident reporting protocols to include heat-related symptoms
-
• Assign responsibility for ongoing compliance
Final Thoughts: Proactive Is Protective
The OSHA heat program isn’t just another regulatory hurdle—it’s a wake-up call. Heat-related illnesses are increasing. This program gives employers the chance to address hazards before they turn into tragedies.
Being proactive doesn’t just meet compliance—it saves lives.
